Patented May 2, 1933 PATENT OFFICE FRANCIS I-I. SHERMAN, OF PALMER, MASSACHUSETTS PACKING MEANS FOR FRAGILE ARTICLES Application filed August 6, 1928.

My invention relates to means for packing or packaging fragile articles, particularly eggs, and aims to provide improved, simplified and less expensivcly 4manufactured article holding devices or partitioning or filler means for'use in connection either with smaller packages as employed in the retail trade or with larger lots such as crates for wholesale use or shipment.

Fig. 10 is a similar View illustrating a separate closure or cover.

Referring more particularly to the drawings, and first to Figs. 1 to 4, the partition forming and cushioning means in accordance with my invention is moulded, embossed, stamped or otherwise constructed in sheet or other form preliminary to use. Various lna- Serial No. 297,629.

terials may be-employed for the purpose, including boxboard, cloth or cloth-reinforced cardboard, Celluloid, etc., but preferably it is of a cellulosic or fibrous nature, such as pulp of any kind, pulp board, disintegrated paper molded or felted, if desired, or other suitable material preferably of sufficient inherent rigidity to be self-supporting yet iexible or elastic in the manner of diaphragm.

In Fig. l, I have illustrated a completely formed but unfolded sheet adapted to be set up or folded and secured, for example, as in Fig. 2, to provide a plurality of rows of cells or compartments, there being six rows of six cells each in the device as shown. The sheet element, indicated as a whole at 1 in Fig. l is provided with transverse fold lines or is transversely creased, scored or otherwise formed for folding, demarking it into a plurality of parallel strips comprising side walls 2, 2, etc., and in the present illustrativev embodiment, bottoms or bottom walls 3, 3, etc., hingedly connected, along said fold lines, to the preceding and succeeding strip. The fold lines between adjacent side wall strips or portions are indicated in Fig. 1 at 2', 2, etc. It will be noted that at opposite ends of the sheet are single side Wall strips 2 while throughout the remainder of the sheet the side wall strips are in pairs, and, in this instance, with a bottom Wall strip or cushion 3 intermediate each such pair. That is, the

sheet member as a Whole is foldable to form a trough or channel element, or to form a. plurality of such elements in substantial parallelism, eachto receive or position an egg or other article or a row of two or more such articles.

Each side-Wall strip 2 is similarly formed witha series of alternating and comparatively high raised portions or projections 4, 4, etc., and comparatively low cushions or elevated portions 5, 5, etc. serving also as strengthening ribs. Said projections 4, 4, in the set-up condition of the device constitute transverse` partition elements, forming, preferably but not necessarily with like means on the bottom walls, the divisions between the indi-4 vidual cells or cbmpartments of a row, as Well as serving as cushioning means lengthwise the 100 row. As illustrated, they are of a mound-like form, resembling truncated and somewhat rounded pyramids, but they may be variously shaped and proportioned, as to height, breadth and length and as to angularity, eX- tent of rounding, etc. Depending on the material employed, said formations 4 and 5 are produced in the original moulding of the pulp material, or are embossed from a fiat sheet, o r otherwise produced.

The bottom strips 3, if separately folded bottom strips are employed, may be formed identically as the side-wall strips, for example, as shown at '3a in Fig. 5. including alternating high and low projections. As illustrated in Figs. l to 6 each bottom strip includes the relatively high raised parts or partitioning and cushioning members G, 6, etc., in registry with the like formations 4, 4 of the side walls. Intermediate said relatively high projections G, G are the relatively low raised portions, ridges or ribs 7, 7, etc. of a width corresponding to that of the side cushions and strengthening ribs 5, 5, etc. These ribs 7 receive the lower extremity of the article to be positioned and cushion and elastically support it. Said ribs 7 may be of the same height throughout their length, as shown in Fig. 5,A being then substantially identical with the side members 5, 5, etc., or they may be formed at or near their opposite ends with higher portions or cross ribs as indicated at 8, 8, etc., in Figs. 1 to 4, whereby each cell or compartment bottom is given an elastic base or receiving formation in which the end oi the egg or other article may rest. Said cross ribs 8 may terminate at the side edge of the ridges or ribs 7 from which they rise, as illustrated, having valleys between them and the high projections or partition members 6 at each side, or may extend across and merge into said members 6, or may be more or less curved, or otherwise formed.

It will be understood from the illustrative views that the higher or partition parts 4, 4, etc., of the side-wall strips which are to form the opposite side walls for a given row of cells or compartments, and the higher or partition parts 6, 6 of the bottom strip ol" that row -are in registry, while their inclined ends permit them to miter at the lower corners of each compartment, see Fi gs. $1, 5 and so that together they form a substantially continuous partition, down on`e side, across the bottom and up the opposite side in any given row. The contents of each cell, such as an egg E, Fig. 2, are thus positioned and cushioned on all sides and also-at the bottom. The parts described are particularly adapted to cooperate in cushioning and positioning globular articles such as eggs, the converging walls of the several partitioning or raised parts 4 and 6 conforming to the contour of the egg or likeformed article, as best seen for example in Fig. 6, again to be referred to later'. From said iigure it will be observed that the eggs 'E have substantially an all-round support and cushion, at four points by the partition members 4 and at two additional points by the lower' or side cushions 5. In addition to this they may also be cushioned or positioned as by an elastic base at their bottoms, in the manner already described. It will further be noted that the side partition members 4 desirably terminate short of the side wall upper edges, and below the top of a positioned egg of normal size, thus leaving a relatively flat upper edge portion for the side walls. These upper edge portions may be strengthened and given additional rigidity by extending the lower raised portions or ribs 5 above the partition members 4, and to or nearly to the extreme upper edge of the side walls, as indicated at 5a in the several figures. A plurality of the multiple row fillers of Figs. 1 to 4 may accordingly be super-posed, preferably with alternate layers having their rows arranged at right angles, the side walls being suiiciently rigid to support the several layers, with or without the use of separate flats between layers. The same is also true with the fillers having a less number of rows of cells, such as the two-row iillers of Figs. 6, 7 or 8.

By reason of the illustrated construction, wherein the side partition members 4 are of a less height than the side walls, the contained articles such as the eggs E are much more fully displayed than with the ordinary interlocked-strip filler, and afford the further marked advantage ,thereover of providing continuous air-passages of substantial crosssection throughout the full length of each row of cells, one intermediate the egg and each side wall, giving complete ventilation to the filler contents.

When the means of my invention employed as for packing eggs in a standard SiO-dozen crate, a sheet as illustrated in Fig. l and formed as described is set up or folded along the hinge lines 2 provided for the purpose intermediate the adjoining strips, into the form as in Fig. 2. Desirably the binge formations are such that the sheet tends naturally to approach the condition as in Fig. 2, whereby the several cell rows readily assume said form merely by pushing inwardly from the opposite ends of the sheet as a whole. The internal side walls are thus of double thickness, the two strips of each pair being brought together flatwise and in opposition, with their respective partition projections 4 oppositely disposed base to base.

Any suitable means may be provided for retaining the device in position as in Fig. 2. and I have illustrated for the purpose a tie or lock-wire S) extending through openings 10, 1() in the outer side-wall strips and having upset ends 11, 1l to engage the outer face of is to be the latter. The remaining side walls are provided with registering slots or apertures 12, 12, etc., for the reception of said tie 9, or used with a band, cardboard or other material; or tray.

It will be understood that the described partitioning, cushioning and filler means of my invention provides a combined flat and filler for use either with the regulation flat between layers or without such eXtra flat, If desired each succeeding layer may have its cell-rows disposed at right-angles to those of the preceding layer. In the 6 X 6 form as shown in Figs. 1 and 2 my filler device may be proportioned to tit one-half of a standard ,d0-dozen egg crate, and in such case, as stated, it may take the place both of the flat or cushioning sheet usually placed between the succeeding layers of eggs, and also of the cellular filler, generally formed of interlocked longitudinal and cross strips'. It may readily be lifted as a unit, and in the manner of a tray. y

The described filler means is equally applicable for use in connection with smaller receptacles or packages such as al standard 2 X 6 egg carton, or other forms such as 2 X 3, 1X 6, etc. In Fig. 6 I have illustrated it in connection with a 2 X 6 carton, the filler comprising but two rows of siX cells each. Further my invention contemplates the use of the same filler device in which the articles or eggs are contained in the larger lot or crate, as for shipment, for packaging in the smaller lots such as the 2 X 6 carton. To effect this, it is necessary merely to separate the desired number of cells or rows of cells into the required groups of cells or package units, eitherv in the direction ofv the rows, or crosswise thereof, or both. If desired, the larger unit of Figs. l and 2 may be perforated or otherwise arranged for ready detachment along the desired lines to provide such number and arrangement of smaller units as circumstances require. As one example only I have indicated at 13, 13 in F 1, perforations or the like whereby the 6 X 6 device may be separated into three 2 X6 fillers.

This use of a combined flat`7 and filler separable into smaller' unit fillers is particularly advantageous where the eggs eo..- tained in the larger unit have been sealed as by coating with paraliin and accordingly do not require further candling before they are distributed or packaged for retail sale. vObviously the fillers may be originally formed in such smaller units when desired.

In Fig. 7, I have shown a double-row filler, generally similar to that of Fig. 6, employed in conjunction with a tubular or sealed carton or wrapper 14, in which it is retained by stapling or other connection at one or both ends, as indicated at 15, 15. In this manner it is particularly useful in connection with the means and method disclosed and claimed in my prior Pat-ent N o. 1,588,857, dated J une 15, 1926.

In some instances I may provide, in addition to opposite side and bottom walls for thev one outer sidewall, as at 17 or being divided and hinged to the two opposite outer side walls. In practice I have found such provision of a top generally unnecessary, as the bottoni wall of any superposed carton or filler therein serves as a cushion at the top of the under ller or carton'. Said top may be use- .ful, however, in case it is desired to employ,

the filler separately, as a receptacle with or without other container or with or without a wrapper. Said top or side-wall extension 16 may, if desired, and particularly if the illustrated receptacle is to be used as a complete package, include a closure lip or flap 16a, and any suitable means 18, such as a clip, wire, gummed sealer or the like may be provided for securing it in closed position. Also the inner or opposed side walls 2, 2 may be secured against possible separation in any uitable manner, as by the gummed strip 19,

The described construction providing atop for the receptacle is equally applicable to single row units as to plural row units, each row including one or more pockets or cells. In Fig. 9, for eXample, is illustrated a unit of one pocket or cell in width and of any desired number of pockets or cells in length, having one side-.wall 2 extended as at 16 to provide a top wall which may terminate at the opposite side wall or be formed with the flap or lip 16a., as preferred. Preferably such top strip or strips is or are formed with the projections 4a, 4a, etc. similarto the projections 4 of the bottom strip or strips. In such case said projections are located on`all four walls of each pocket or cell, that is, on the bottom, opposite sides and top, as shown. A completely closed and cushioned pocket for each -article or egg is thus provided. The constructions illustrated in Figs. 8 and 9, particularly when made with a view to their use as complete packages, may be referred to as unitary egg receptacles. It will be understood that the side-wall extensions, or tops may likewise be employed, either with or wiQout the end flaps or lips, when said receptacles are to be used within a carton or wrapper, or in a crate or the like.

Referring to Fig. l0, I have illustrated another form of closure, comprising aseparate cover member 20, of inverted U-shape,

the sides 21, 2l of which may extend downward any suitable distance on the cell sides and may be sealed or otherwise secured thereJ to by any suitable means. Such member may be employed with receptacles of one or more cells in width and/or length, and the latter may be open-topped or closed-topped, as described in connection with Figs. 8 and 9, and if desired said member 20 may itself be formed with the projections 4a, for use with open-topped receptacles, thus providing continuous or all-round positioning and cushioning means for the contents, or it may be a flat-surfaced member, without projections, and more readily adapted to receive printed matter.

The numerous advantages of the means ofmy invention will be apparent from the foregoing description taken in connection with the drawings. In addition to the resulting safety and practical elimination of breakage. the described partitioning or filler means may be made to afford increased ventilation for the contents, the partitioning parts being constructed and arranged to afford free passage of air throughout the entire length of any row of cells, as clearly apparent in Fig. 2. In said connection the carton, wrapper or other outer receptacle may be open-ended as in Fig. 7, or it may have its end walls recessed, apertured or reduced as indicated, for eX- ample, at 22, 22, Fig. 6, to facilitate a through draft. rllhe ventilation may be further increased by the provision of apertures in the sides or bottom, which apertures may also. provide drainage for an occasional broken egg, preventing contamination of the other eggs.

rllhe means of my invention also affords more attractive display of the contents, as the relatively low partitioning and cushioning` parts did not obscure them, whether eggs or other articles, but cause them to stand out distinctly and in full View. `Obviously the proportion, shapes and heights of the described partitioning and cushioning parts may be varied, and the latter may be otherwise formed than as herein illustrated by way of example.
